Multicenter Study Comparative Study
Risk factors for cardiovascular disease in people with idiopathic pulmonary fibrosis: a population based study.
People with idiopathic pulmonary fibrosis (IPF) have been shown to be at an increased risk for cardiovascular (CV) disease, but reasons for this are unknown. The aim of this study was to compare the prevalence of common CV risk factors in people with IPF and the general population and establish the incidence of ischemic heart disease (IHD) and stroke after the diagnosis of IPF, controlling for these risk factors. ⋯ Several CV risk factors were more prevalent in people with IPF; however, this did not account for the increased rate of IHD in this group of patients.

The advances in PET scanning for thoracic diseases that are deemed most likely to have clinical impact in the near-term future are highlighted in this article. We predict that the current practice of medicine will continue to embrace the power of molecular imaging and specifically PET scanning. 18F-fluorodeoxyglucose-PET scanning will continue to evolve and will expand into imaging of inflammatory disorders. ⋯ These will result in significant improvements in image quality, improving the evaluation of smaller lung nodules and metastases and allowing better prediction of prognosis. The birth of clinical PET/MRI scan will add new imaging opportunities, such as better PET imaging of pleural diseases currently obscured by complex patient motion.

Undifferentiated connective tissue disease (UCTD) involves conditions characterized by both having symptoms of connective tissue disease (CTD) and autoantibodies but not fulfilling the criteria of a specific CTD. The frequency or prognosis of the usual interstitial pneumonia (UIP) pattern in UCTD is unknown, which may be confused with idiopathic pulmonary fibrosis (IPF). This study aimed to investigate the frequency of the UIP pattern in interstitial pneumonia related to UCTD and compare its prognosis with that of IPF and UCTD-nonspecific interstitial pneumonia (UCTD-NSIP). ⋯ A UIP pattern, which seems to be frequent in UCTD, showed a poorer prognosis than that of UCTD-NSIP. However, the prognosis of UCTD-UIP was significantly better than that of IPF, highlighting the importance of searching for underlying UCTD in suspected IPF cases.

Case Reports
A 44-year-old woman with metabolic acidosis, high anion gap, and delayed neurologic deterioration.
A 44-year-old woman was brought to the ED from John F. Kennedy International Airport. The patient was returning with her son from a 3-month visit to Bangladesh. ⋯ Upon landing, she started complaining of shortness of breath. After disembarking, she was witnessed to have seizure-like activity with involuntary passage of urine, following which she collapsed. The patient was intubated by emergency medical services in the field.

Elevated urinary albumin-creatinine ratio (UACR) and decreased estimated glomerular filtration rate (eGFR) predict all-cause mortality, but whether these markers of kidney damage and function do so in adults with obstructive lung function (OLF) is unclear. The objective of this study was to examine the associations between UACR and eGFR and all-cause mortality in adults with OLF. ⋯ UACR and eGFR, in continuous form, were associated with all-cause mortality among US adults with OLF.
